The ep, slated to air this fall, finds Castle and Beckett investigating a death at a science fiction convention, thrusting them into a “world of egotistic celebrities, diehard fans and enough drama for two galaxies,” previews series creator Andrew Marlowe, who first floated the possibility of a Con-inspired episode to TVLine earlier this month.

This marks Frakes’ second turn behind the Castle cameras. He previously helmed the Season 2 outing, “Kill the Messenger.”

everything has been done by someone somewhere, there are no original ideas anymore. anyway who cares if someone else done it, its about how good it is not who can do it first, if that was the case we would have given up telling stories years ago

Murder investigations on TV have been done as well. Including high-tech ones. Castle’s never been about innovative new concepts in crime-fighting. Like Castle’s books, it’s supposed to be high-quality pulp, a fun ride that’s light on its feet and a joy to watch. It’s when the show has its occasional Very Special Episode that things turn dramatic, and when they have too many of those in a row (as in season 5), things start to drag. Castle at its best is about having a blast with the journey.

Frakes directed the great episode, Kill the Messenger, back in season 2, so I’m hoping this measures up. Ironically, the easiest place to go on location– at a real con –isn’t really feasible, since Nathan Fillion and Jonathan Frakes are such rock stars that filming wouldn’t be possible. Castle’s Season 2 script editor Jose Molina isn’t exactly a household name…. except among Firefly fans, who would probably swoon if he came back into the family as well.

Cameos from Star Trek or Firefly alums are welcome, but I’m not holding my breath. I’m happy enough that we saw Adam Baldwin last spring, and hoping he re-appears from time to time. Seeing Jewel Staite or Sean Maher or Alan Tudyk would rock. Could Castle afford to pay for a Neal Patrick Harris cameo? Or Morena or Ron Glass or Summer Glau or…? OK, I need to calm down here.

The CSI episode had cameos from cast members from Battlestar. Ron Moore’s was very good. If Castle did an episode at a science fiction con with cameos by cast members from Firefly, it be using the same formula.

Thirded! (not sure that’s a word but this Writing degree-holder doesn’t care!) This is pretty much the only TV news site that I visit that gives Castle lots of love (although I don’t visit of them). It’s one of my favorite sites to visit :)

so he’s going to have a cameo right, you cant pull in a director famed in sci fi for an episode with this premise without him having a cameo. also if felicia day could cameo as a character called penny that would be awesome

I don’t think they are borrowing ideas from CSI and other shows. They just want to give more nods to Firefly. The premise really just sounds like a way to make Firefly references to me. Which is awesome, I might add.
